Hello,
use:
modparam("htable", "htable",
"isp=>size=8;dbtable=isp;cols=ispname,ispip,ispuser,ipsprefix,ispprefix")
then you have the $sht(ispname) with value corresponding to
"ispip,ispuser,ipsprefix,ispprefix" and then you can use {s.select,,0}
to get ispname value, then {s.select,,1} to get ispip value, etc...
An alternative would be to keep only two columns in database, one (the
key) with ispname and the second (the value) all fields serialized in a
json document and you use jansson to parse them in config.
Cheers,
Daniel

Hello,
What will be the best way to save ISP Information in Kamailio memory?
I have the following information for each ISP into the DB:
*ISP Name | ISP IP | ISP Username | ISP Password | ISP Prefix*
ISP1 | 1.1.1.1 | user |
pass | 1234*
*
This info it's not changed/updated too often, so I want to avoid
querying the DB on every call and get this info directly from the memory.
I was thinking to use htable for that, so I created a htable as an
array for that and loaded all the information there manually,
something like that:
*kamcmd htable.sets isp ISP1[address] 1.1.1.1*
*kamcmd htable.sets isp ISP1[username] user*
*kamcmd htable.sets isp ISP1[password] pass*
*kamcmd htable.sets isp ISP1[prefix] 1234
*
*
*
*$sht( isp => ISP1[address]) == "1.1.1.1"*
*$sht( isp => ISP1[username]) == "user"
*
*$sht( isp => ISP1[password]) == "pass"
*
*$sht( isp => ISP1[prefix]) == "1234" *
So far so good, I'm able to get this information from the htable and
use it whenever I need it.
Now, the problem comes when I want to load all this information
automatically from the DB. How can I setup htable module to get the
array key (address, username...) from the database automatically on
server restart, and append this array_key to the column value?
I've tried this way:
modparam("htable", "htable", "isp=>size=8;dbtable=isp;cols='trunk_name[address],trunk_address'")
But it's not working unfortunately, getting back this error: You have
an error in your SQL syntax; check the manual that corresponds to your
MariaDB server version for the right syntax to use near '[address]'
If I'm setting this way:
modparam("htable", "htable", "isp=>size=8;dbtable=isp;cols='trunk_name,trunk_address'")
and setting trunk_name value to: ISP1[address], then it's working
fine, but in this case I will have to create by one column for each
array key, which may be confusing and it's a lot of unnecessarily
information into the DB.
Is it possible to do that, or better to trigger a script on each
restart which will load this information from the DB into htable?
Thanks
